CONVEYER OF THE BELT TYPE.

Application filed January 14. 1928, Serial No 246,778, and in GreatBritain January 18, 1927.

This invention, which refers to conveyors of the belt type, relates to asupporting structure for rollers for the belting to travel on, to ashelter for the lower run of the belting, and to construction andarrangement of the members generally.

According to this invention a supporting structure compriseslongitudinal units of inverted trough formation. each unit having aroofing and dowinvardly extending sides, connection means, forconnecting together units of the structure arranged end to end with anintervening space between adjacent ends, the connect-ion meanscomprising a roofing over the intervenin space, and pedestals at theends of the units for supporting the structure.

The connection of two units end to end may be made partly by a platearranged to extend from the roo g of one unit to the roofing ofthe'adjacent unit and form a roofing over the intervening space, andpartly by carriers extending across the intervening space between theadjacent ends of the two units, a

- carrier at each side. Mountings for rollers for the upper run of thebelting are provided on the units and mountings for rollers for thelower run of the belting are provided on the carriers. With a supportingstructure of this description the upper run of the belting is situatedabove the roofin and the lower run of the belting is situated below theroofing, and protection for the lower run of the belting at the sides isprovided by the downwardly extending sides of the units, eX- cept at thepositions where the lower rollers are mounted. At those positionsroofing protection is provided, and the under rollers are visible andaccessible from the sides. The downwardly extending sides of a unit andthe position of the under rollers may be such that the lower edges ofthe downwardly extending sides are as low or lower than the underside ofthe under rollers.

For supporting the units at adjacent ends on each side pedestals may beformed as separate parts or a carrier may be formed to comprisepedestals. For example, in one arrangement the pedestals providedcomprise two pedestals at each end of a unit, each unit thus having fourpedestals, and, at each side, on two adjacent pedestals a carrier ismounted. In another case, two carriers, one at each side, extenddownwardly to act as pedestals, thus, a carrier and pedestals for oneside cross sectional views, the sections being at 2 and 3 of Figure 1respectively, illustrating one construction.

Figure 4 is a side elevation showing portions of two units, and Figures5 and 6 are cross sectional views, the sections being at 5 and 6 ofFigure 4 respectively, illustrating another construction.

The drawings show. Units A of inverted trough formation. each unithaving a roofing 7 and downwardly extending sides 8. Plate B roofingover the intervenin space between adjacent ends of units A. arriers Cextending across the intervening space. Mountings 9 for rollers D.Mountings 10 for roller E. Rollers D are for the upper run and roller Efor the lower run of the belting F. Straps 11 for the mountings 9 andtransverse ties 12.

In the example as illustrated in Figures 1 and 2 the units A andcarriers C are supported on pedestals 13.

In the example as illustrated in Figures 4 and 5 each carrier C extendsdownwardly at 14 and forms a pedestal on which the units A aresupported.

I claim 1. A supporting structure for rollers of a conveyor of the belttype, comprising longitudinal units of inverted trough formation, eachunit having a roofing and downwardly extending sides, connection meansfor connecting units arranged end to end with an intervening spacebetween their adjacent ends, said connection means comprising a roofingextending longitudinally over'the intervening space, carriers extendinglongitudinally across said intervening space, one carrier at each side,said carriers being at a distance below the level of the roofing,mountings on the longitudinal units for rollers for the upper run of thebelting, mountings on the carriers for rollers for the lower run of thebelting, the upper run being above the roofing the lower run being belowthe roofing, and pedestal supports at the ends pf tliile longitudinalunits, for the purposes set ort 2. A supporting structure for rollers ofa conveyer of the belt type, comprising longitudinal units of invertedtrou h formation, each unit having a roofing an downwardly extendingsides, units of the structure being arranged end to end with a spaceintervening between their adjacent ends, a plate roofing over theintervening space, carriers extending longitudinally across saidintervenin space fora roller for the lower run of the elting, onecarrier at each side, mountings on the longitudinal units for rollersfor the upper run of the belting, the upper run of the belt in beingabove the roofing the lower run being below the roofing, and pedestalsuports at the ends of the longitudinal units, or the purposes setforth.

3. A supporting structure for rollers of a conveyer of the belt type,comprising longitudinal units of inverted trough formation, each unithaving a roofing and downwardly extending sides, connection means forconnecting units arranged end to end with an intervening space betweentheir adjacent ends, said connection means comprising a roofingextending longitudinally over the intervening space, carriers extendinglongitudinally across said intervening space for a roller for the lowerrun of the beltin one carrier at each side, mountings on t elongitudinal units for rollers for the upper run of the belting, theupper run being above the roofin the lower run being below the roofing,and pedestal supports formed as integral arts with the carriers, for thepurposes set orth. 4. A supporting structure for rollers of a conveyer othe belt type, comprising longitudinal units of inverted troughformation, each unit having a roofing and downwardly extending sides,units of the structurebeing arranged end to end with an interveningspace between their adjacent ends, a plate roofing over the interveningspace, carriers extending longitudinally across said intervening space,one carrier at each side, said carriers eing at a distance below thelevel of the roofing, mountings'on the lon itudinal units for rollersfor the upper run 0 the belting, mountings on the carriers for rollersfor the lower run of the belting, the upper run being above the roofingthe lower run being below the roofing, and pedestal supports supportsformed as downwardly extending arts of the carrier, for the purposes setorth.
